I can get the Natural Earth data to display. Neat.
How do I enter a point, a bearing from that point, and a distance from
that point, plot the point, the bearing line, and, the distance arc?

If you have lots of polygons, you probably need to look into
v.rast.stats2 , an addon

I wrote a script to do something like this at one point, though I can't find
it now. It was intended for terrain, but could be used per band on imagery.
It used r.buffer to create a distance gradient and then r.recode to convert
this gradient to a percentage. I then used r.mapcalc to merge the 2
In GRASS, one thing you can try is to normalize your data so the variations
from scene to scene are minimized. ie, run a linear regression between
overlapping maps and then use the coefficients to normalize one of the data
sets. However, it is tedious and doesn't work well if the two images arn'

If you want to deal with raster value types other than CELL, you can use the –c
flag in r.statistics in order to process the labels. Therfore, you have to copy

Unfortunely it only works with CELL values. For instance, r.median uses more
than just CELL.
Is there any other alternative? Beucase for mode and median there is
specific functions.
